29Configuration procedureThis example assumes that the system names of Device A, Device B and Device C are DeviceA, DeviceB,and DeviceC, respectively, before the IRF fabric is formed.1. Assign member IDs:# Keep the default member ID of Device A unchanged.# Change the member ID of Device B to 2. system-view[DeviceB] irf member 1 renumber 2Warning: Renumbering the switch number may result in configuration change or loss.Continue? [Y/N]:y[DeviceB]2. Power off the member devices, connect IRF links as shown in Figure 13, and power on the twodevices.3. Configure IRF port bindings:# Bind Ten-GigabitEthernet 1/1/2 to IRF-port 1/2 on Device A and save the configuration. system-view[DeviceA] interface ten-gigabitethernet 1/1/2[DeviceA-Ten-GigabitEthernet1/1/2] shutdown[DeviceA-Ten-GigabitEthernet1/1/2] quit[DeviceA] irf-port 1/2[DeviceA-irf-port1/2] port group interface ten-gigabitethernet 1/1/2[DeviceA-irf-port1/2] quit[DeviceA] interface ten-gigabitethernet 1/1/2[DeviceA-Ten-GigabitEthernet1/1/2] undo shutdown[DeviceA-Ten-GigabitEthernet1/1/2] save# Bind Ten-GigabitEthernet 2/1/1 to IRF-port 2/1 on Device B and save the configuration. system-view[DeviceB] interface ten-gigabitethernet 2/1/1[DeviceB-Ten-GigabitEthernet2/1/1] shutdown[DeviceB-Ten-GigabitEthernet2/1/1] quit[DeviceB] irf-port 2/1[DeviceB-irf-port2/1] port group interface ten-gigabitethernet 2/1/1[DeviceB-irf-port2/1] quit[DeviceB] interface ten-gigabitethernet 2/1/1[DeviceB-Ten-GigabitEthernet2/1/1] undo shutdown[DeviceB-Ten-GigabitEthernet2/1/1] save# Activate IRF port configuration on Device A.[DeviceA-Ten-GigabitEthernet1/1/2] quit[DeviceA] irf-port-configuration active# Activate IRF port configuration on Device B.[DeviceB-Ten-GigabitEthernet2/1/1] quit[DeviceB] irf-port-configuration activeAfter the IRF port configuration is activated, the two devices automatically elect a master. In thisexample, Device A is the master. Device B automatically reboots and joins the Device A as asubordinate switch to form an IRF fabric. The system name of the IRF fabric is DevcieA.4.
